,
1. t WH must be met for both BUSY input (71V421, slave) or output (71V321, master).
2. BUSY is asserted on port 'B' blocking R/ W ' B' , until BUSY 'B' goes HIGH.
3. t WB is for the slave version (71V421).
4. All timing is the same for the left and right ports. Port "A" may be either the left or right port. Port "B" is oppsite from port "A".

NOTES:
1. All timing is the same for left and right ports. Port “A” may be either left or right port. Port “B” is the opposite from port “A”.
2. If t APS is not satisified, the BUSY will be asserted on one side or the other, but there is no guarantee on which side BUSY will be asserted (71V321 only).
